Zeobond Pty Ltd
E-Crete is made of fly ash (by-product of burning coal at a power station), slag (the by-product of steel manufacturing), and geopolymer.
E-Crete uses industrial by-products and geopolymer to produce concrete. It has been found to reduce CO2 by at least 60% compared to Ordinary Portland Cement.
Users who looking for an alternative to ordinary Portland cement based concrete for construction and infrastructure
E-Crete is a mixture of fly ash, slag, and geopolymer, and it can be used similarly to traditional Portland cement-based concrete.
Patented and Trademarked
Users can obtain the product/service from Zeobond group website.

E-Crete is specified by 25, 32, 40 and 55 MPa, and it reduces the embedded carbon dioxide of concrete by at least 60% compared to Ordinary Portland Cement.
Manufacturer specified performance targets include reducing embedded CO2 of the concrete as well as having a fire rating of over 4 hours.
Strength development profiles for E-Crete™ can achieve the nominal values of 20, 25, 32, 40, and 50 MPa within 100 days.
